Test Procedure:

1.Unplug the grinder.

2.Connect a voltmeter across contacts 1 & 2 of the larger connector (P4) on the timer board. Plug-in the grinder. The indication must be 120 volts ac for 120V models and 230 volts ac for 230V models.

3.Unplug the grinder.

4.Connect a voltmeter across contacts 2 & 6 of the larger connector (P4) on the timer board. Plug-in the grinder. When the control switch is in any posi- tion except “OFF” (center), the indication must be 120 volts ac for 120V models and 230 volts ac for 230V models.

5.Unplug the grinder.

If voltage is present as described, proceed to #6.

If voltage is not present as described, refer to the Wiring Diagram and check the grinder wiring harness.

6.Connect a voltmeter across contacts 3 & 7 of the larger connector (P4) on the timer board. Plug-in the grinder. Momentarily press the Off/On/Start switch to “START” (lower) position and release. The indication must be 120 volts ac for 120V models and 230 volts ac for 230V models.

7.Unplug the grinder.

If voltage is present as described, proceed to #8.

If voltage is not present as described, replace the timer.

8.Connect a voltmeter across contacts 4 & 7 of the larger connector (P4) on the timer board. Plug-in the grinder. Place the hopper selector switch to the left position. Momentarily press the Off/On/ Start switch to the “START” (lower) position and release. The indication must be 120 volts ac for 120V models and 230 volts ac for 230V models and should remain for the approximate timer setting.

9.Unplug the grinder.

If voltage is present as described, proceed to #10.

If voltage is not present as described, replace the timer.

10.Connect a voltmeter across contacts 5 & 7 of the larger connector (P4) on the timer board. Plug-in the grinder. Place the hopper selector switch to the right position. Momentarily press the Off/On/ Start switch to the “START” (lower) position and release. The indication must be 120 volts ac for 120V models and 230 volts ac for 230V models and should remain for the approximate timer setting.

11.Unplug the grinder.

If voltage is present as described, the timer is operat- ing properly.

If voltage is not present as described, replace the timer.

Removal and Replacement:

1.Separate the grinder wiring harness connectors from the timer circuit board.

2.Remove the relay from the timer bracket.

3.Attach the relay to the new timer bracket.
